But is it ?

I think it's right on the borderline for classification, wetting agents are longer chains. A 2nd Kodak patent has quite similar although more complex organic compounds sulphonates/sulphonic acid salts as antioxidants but they aren't long chain.

In the Kodak PPD/Benzenesulfonate Patent they say it's used to help PPD dissolve, that's nonsense it's there for another reason.

There's some misinformtation in these early Patents, later Fuji hide it, although newer Patents are more open.

You can use a detergent as an Insecticide, or a soap, spray a solution of it on the insects and they drown, but if it's an antioxidant it'll be better
